Multiple Choice C++ Quiz
 Unit 4 - Looping
 

Directions:  Choose the best answer.  Use the button at the bottom
to check your answers.

1.  Each pass through a loop is called a/an
     [a] enumeration
     [b] iteration
     [c] culmination
     [d] pass through
 

2.  Which looping process checks the test condition at the end of the loop?

     [a] for
     [b] while
     [c] do-while
     [d] no looping process checks the test condition at the end

3.  A continue statement causes execution to skip to

     [a] the return 0; statement
     [b] the first statement after the loop
     [c] the statement following the continue statement
     [d] the next iteration of the loop

4.  In a group of nested loops, which loop is executed the most number of times?

     [a] the outermost loop
     [b] the innermost loop
     [c] all loops are executed the same number of times
     [d] cannot be determined without knowing the size of the loops

5.  The statement  i++;  is equivalent to

     [a] i = i + i;
     [b] i = i + 1;
     [c] i = i - 1;
     [d] i --;

6.  Which looping process is best used when the number of iterations is known?

     [a] for
     [b] while
     [c] do-while
     [d] all looping processes require that the iterations be known

7.  What's wrong?  for (int k = 2, k <=12, k++)

     [a] the increment should always be ++k
     [b] the variable must always be the letter i when using a for loop
     [c] there should be a semicolon at the end of the statement
     [d] the commas should be semicolons

8.  What's wrong?  while( (i < 10) && (i > 24))

     [a] the logical operator && cannot be used in a test condition
     [b] the while loop is an exit-condition loop
     [c] the test condition is always false
     [d] the test condition is always true

9.  If there is more than one statement in the block of a for loop, which of the following must be placed at the beginning and the ending of the loop block?

     [a] parentheses ( )
     [b] braces { }
     [c] brackets [ ]
     [d] arrows < >

10.  What's wrong?  (x = 4 && y = 5) ? (a = 5) ; (b = 6);

     [a] the question mark should be an equal sign
     [b] the first semicolon should be a colon
     [c] there are too many variables in the statement
     [d] the conditional operator is only used with apstrings
